This week, motherboard manufacturers started releasing new BIOS versions for their Socket AM4 platforms based on the new AGESA 0070 version. Updates are already available for many ASUS, Biostar and MSI motherboards based on the X470 and B450 chipsets. Among the main innovations coming with these BIOS versions is “support for future processors”, which indirectly indicates the beginning of the phase of active preparation of AMD partners for the release of representatives of the Ryzen 3000 family - the expected 7nm chips built on the Zen 2 architecture.
Such an important event could not be ignored by enthusiasts, and the new BIOS for one of the Biostar boards was dissected by Reddit users. As a result of the reverse engineering, some interesting details came to light. And the biggest surprise is that the UEFI BIOS menu with basic processor settings, previously called Zen Common Options, will be called Valhalla Common Options when new CPUs are installed on boards. And this can only mean one thing: AMD is going to use the codename Valhalla (Valhalla) as the name of the architecture of the future Ryzen 3000 or platform for them.
There is another change in terminology. Instead of the abbreviation CCX (CPU Core Complex), for the modules from which the Ryzen 3000 will be assembled, a different abbreviation is used - CCD, which probably stands for CPU Compute Die (CPU Compute Die). The change in terminology in this case is quite justified, since in future processors all I/O controllers have been moved to a separate 14nm I/O chiplet, while 7nm processor chipsets will contain exclusively computational cores.
Unfortunately, the BIOS code does not make it clear what the maximum number of cores future Ryzen 3000s can get. There are options in the settings list that allow you to activate and deactivate up to eight CCDs, but, obviously, this code snippet is copied from the BIOS for EPYC Rome - server processors , which can contain up to eight chiplets with processor cores.
The appearance of support for Ryzen 3000 in the BIOS of motherboards may mean that AMD plans to start sending out engineering samples for debugging and system validation in the near future. In other words, preparations for the announcement are in full swing, and there should not be any delays. AMD is expected to introduce desktop processors based on the Zen 2 architecture in early July.
